Definition: A flag lot shall be described as containing an area shaped like a "flag" which is the portion of the lot where all structures are to be located and an area shaped like a "pole" which is the portion of the lot where the vehicular access between the flag and its adjoining road shall be located.

(4) 
An initial concept sketch shall be submitted with all flag lot applications showing the width of the pole of the flag lot at no less than 50 feet (40 feet in the R-9 zone). The flag portion of the lot shall meet the lot area requirement for the zone excluding the pole portion of the lot. Once this has been demonstrated the applicant may seek approval for a plan submitted with the application showing:

The width of the pole reduced to no less than 20 feet; and
b. 
The front lot conforming to all of the requirements for the zone.

The mean prevailing front yard setback to be applied to a lot shall be determined as follows:
(a) 
The front yard setback for the principal dwellings on each lot fronting on the same side of the street within 500 feet in either direction of the lot for which the prevailing front setback is to be measured and within the same zoning district shall be determined. The measurement shall not include the setback from the street for corner lots, where the front yard of the corner lot is measured from a different street. In calculating the mean prevailing setback, the largest and smallest setback shall not be included in the calculation. Setbacks shall be measured to the nearest part of the house excluding porches and stoops.
(b) 
If the mean prevailing front setback as calculated for a lot is more than five feet or less than five feet of the required minimum setback, the building setback shall be within two feet of the calculated mean setback.
(c) 
If the mean prevailing setback as calculated for a lot is not more than five feet greater or five feet less than the required setback, then the developer shall comply with the minimum required setback.
(d) 
If utilization of the mean prevailing setback would limit the construction of a dwelling to a size which is less than 80% of the maximum building size permitted in the district, then the mean prevailing setback shall be adjusted to a setback which permits the construction of a dwelling which is 80% of the maximum building size permitted in the district, for a lot with the minimum lot size but not less than the minimum required front yard setback.
(e) 
If a street contains three or fewer dwellings then the property owner shall have the option to match either front yard setback.
